Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention provides a lock structure of the
connector assembly, and more particularly to a handle pivoted on a
plug connector of a lock structure can be pushed apart by a
shielding housing when the plug connector is not locked, so as to
make the handle not clasp on the outer metal shell of the socket
connector; after the plug connector is combined on the socket
connector, the handle can be pulled to rotate to elastically return
to original locations, to make the handle clasp on the outer metal
shell, so as to facilitate to perform lock or unlock operation.
2. Description of the Related Art
[0002] Generally, connectors are used as connection device and
auxiliary accessory for electronic signals and power, and the main
function of the connector is to provide connection between various
electronic devices or apparatuses, and to ensure that the signals
can be accurately transmitted. According to different applied
products, power and environment, the connectors have developed a
variety of different types to be widely used in fields of consumer
electronic products such as computers, notebook computers, smart
phones, or fields of household appliances, telecommunications or
communication equipment. The designs of electronic products are
tending to be light, thin, short, and small, the sizes of
connectors inside various electronic products need to be greatly
reduced, and it is more difficult to connect and fasten the thin
connectors with general wires or flexible circuits.
[0003] Furthermore, as the volume of electronic product is getting
thinner and thinner, the components on the circuit board inside the
electronic product must be more precise and miniaturized, and the
overall structural strength also needs to be strengthened. A
general connector, such as a board-to-board connector or a
wire-to-board connector, usually use a male connector and a female
connector for matedly connection, to transmit signal or power to a
control circuit through a circuit board to execute an operation
function; however, in order to reduce the overall structure height,
the male connector is usually connected and assembled with the
female connector by a mounting manner, and a main body of the male
connector is first inserted into a mounting space of the female
connector, and convex buckle of the main body is clasped in the
buckle groove of the base, so that conductive terminals of the main
body can be held in contact with the corresponding contact
terminals on the base to form electrical connection, thereby
achieving the electrical connection between two parallel circuit
boards, or between a flexible circuit board, a cable and a circuit
board.
[0004] However, because the main body and the base are integrally
formed by a colloid made of resin, and the manner of mounting the
main body and the base by buckling the convex buckle and the buckle
groove may cause abrasion due to multiple insertions and
connections, and it causes reduction in the overall mounting force
of the connector; when the connector is assembled or disassembled,
excessive squeeze may also result in damage to the colloid or the
structure of the connector. Furthermore, when the male connector
and female connector are connected, conductive terminals and
contact terminals are connected through frictional contacts between
the single sides thereof, but the fastening effect between these
two terminals is not strong enough, and when the male connector and
the female connector are impacted or touched by an external force,
the male connector may be loosened or separated from the female
connector, and it results in unstable signal transmission between
the male connector and the female connector.
[0005] Therefore, how to solve the above-mentioned problems is a
key issue in this industry.
SUMMARY OF THE INVENTION
[0006] In order to solve the above-mentioned problems, the
inventors develop a lock structure of a connector assembly
according to collected data, multiple evaluations and tests, and
years of experience.

base member of a socket connector of a lock structure can include a
plurality of conductive terminals disposed therein, and the
mounting base member is combined with a base part of an outer metal
shell, and the base part includes two clasping parts disposed on
two opposite side surfaces, respectively; and a base of a plug
connector of the lock structure includes a plug part disposed on a
bottom thereof and combined in the docking chamber, and the base
includes a connection part disposed on a rear side of a top
thereof, and a plurality of contact terminals disposed therein and
electrically connected to a transmission unit fastened on the
connection part, and an outer part of the base is combined with a
main body of a shielding housing, and the shielding housing
includes pushing parts disposed on two opposite sides thereof, and
each of the pushing parts has a groove cut through a side thereof,
and the groove has a shaft hole cut therethrough, and a handle is
pivotally connected to the two shaft holes and configured to be
pulled to rotate, and the handle includes two lateral rods extended
from two ends of the base rod, respectively, and the two lateral
rods have clasping ends inwardly bent from ends thereof relative to
each other and pivotally connected to the shaft hole; when the plug
connector is not locked on the socket connector, the lateral rods
on the two sides of the handle can be pushed by surfaces of the two
pushing parts to be apart from each other outwardly, to make the
two clasping ends of the handle not clasp on two clasping parts of
the outer metal shell; after the plug connector is combined on the
socket connector, the handle can be pulled to rotate, to make the
lateral rods on two sides of the handle align to the two grooves
and return the two lateral rods to original locations elastically,
so as to make the two clasping ends of the handle clasp in the two
clasping parts of the outer metal shell, and the socket connector
and the plug connector can be securely locked integrally, thereby
achieving the purpose of improving simplicity and intuition in
operation.
[0008] Another objective of the present invention is that during
the process where the handle is unlocked and rotated, two inner
side surfaces, opposite to each other, of the two lateral rods of
the handle are guided to slide along guiding surfaces of the two
pushing parts, to make the two lateral rods unlock to rotate
smoothly, thereby achieving the purpose of improving smoothness in
operation.

[0028] Please refer to FIGS. 4 to 8, which are a perspective view
of a lock structure of a connector assembly before a socket
connector and a plug connector are connected with each other, a
sectional front view of the lock structure of the connector
assembly when the socket connector and the plug connector are
connected with each other, and a perspective view, a sectional
front view and a sectional side view of the lock structure of the
connector assembly after the socket connector and the plug
connector are connected with each other. As shown in
[0029] FIGS. 4 to 8, the socket connector 1 can be first
electrically connect the connection terminal 122 of the plurality
of conductive terminals 12 to a plurality of contacts 31 on the a
of a circuit board 3 by the surface mount technology, the
through-hole manner or other electric connection manner; before the
socket connector 1 and the plug connector 2 are matedly connected,
the handle 25 of the plug connector 2 can be upwardly turned in
advance, and the distance (A) between the lateral rods 252 on two
sides of the handle 25 is smaller than the distance (B) between the
supporting surfaces 2424 of the two pushing parts 242, so the
lateral rods 252 on the two sides of the handle 25 are outwardly
pushed apart from each other by the supporting surfaces 2424 of the
two pushing parts 242, to make the base 21 of the plug connector 2
downwardly assemble on the mounting base member 11 of the socket
connector 1 and make the plug part 211 of the base 21 insert into
the docking chamber 111 of the mounting base member 11; at this
time, the contact parts 221 of the contact terminals 22 are in
electric contact with the butt joint terminals 121 of the plurality
of conductive terminals 12, to form an electrical conduction
status.
[0030] After the plug connector 2 is downwardly assembled on the
socket connector 1, the base rod 251 of the handle 25 can be
rotated in the counterclockwise direction, to axially rotate the
two clasping ends 253 of the handle 25 in the shaft holes 2420 on
the two sides of the pushing part 242, so that the base rod 251 of
the handle 25 is rotated to the front of the plug connector 2, and
the two lateral rods 252 of the handle 25 are aligned to the
grooves 2421 of the two pushing parts 242 and forwardly extended
from the openings 2422 of the two pushing parts 242; at this time,
the supporting surfaces 2424 of the two pushing parts 242 are not
abutted against the opposite inner sides of the two lateral rods
252 of the handle 25, so that the two lateral rods 252 of the
handle 25 can elastically return to original locations to make the
two clasping ends 253 of the handle 25 buckle into, and clasped and
fastened with the buckle holes 1321 of the clasping parts 132 on
two sides of the outer metal shell 13; as a result, the socket
connector 1 and the plug connector 2 can be securely locked
integrally.
[0031] In order to separate the plug connector 2 from the socket
connector 1, the base rod 251 of the handle 25 can be rotated in
the clockwise direction, to pull the handle 25 back to the above
location; during the process where the handle 25 is rotated in the
clockwise direction, two inner side surfaces, opposite to each
other, of the two lateral rods 252 of the handle 25 are guided to
slide along the guiding surfaces 2423 of the two pushing parts 242,
and the two lateral rods 252 can be smoothly rotated in the
clockwise direction; at the same time, the lateral rods 252 on two
sides of the handle 25 are outwardly pushed apart from each other
by the supporting surface 2424 of the two pushing parts 242, to
make the two clasping ends 253 of the handle 25 not buckle into the
buckle holes 1321 of the clasping parts 132 on two sides of the
outer metal shell 13, so that the socket connector 1 and the plug
connector 2 can form an unlocked state; next, the plug connector 2
can be upwardly pulled to separate the contact parts 221 of the
plurality of contact terminals 22 from the butt joint terminals 121
of the plurality of conductive terminals 12; as a result, the
operation of the lock structure of the present invention can be
completed.
[0032] According to above-mentioned contents, the lock structure of
the present invention has following advantages.
[0033] First, when the plug connector 2 is not locked on the socket
connector 1, the lateral rods 252 on the two sides of the handle 25
are pushed by the surfaces of the two pushing parts 242 to be apart
from each other outwardly, so as to make the two clasping ends 253
of the handle 25 not clasp on two clasping parts 132 of the outer
metal shell 13; after the plug connector 2 is combined on the
socket connector 1, the handle 25 can be rotated to make the
lateral rods 252 on two sides of the handle 25 align to the two
grooves 2421, to return the two lateral rods 252 to original
locations elastically, so that the two clasping ends 253 of the
handle 25 can be clasped in the two clasping parts 132 of the outer
metal shell 13, respectively, and the socket connector 1 and the
plug connector 2 can be securely locked integrally, and the user
can just use the handle 25 to lock or unlock the socket connector 1
and the plug connector 2 effortlessly, thereby achieving the effect
of improving simplicity and intuition in operation.
[0034] Secondly, during the process where the handle 25 is unlocked
and rotated, the opposite inner side surfaces of the two lateral
rods 252 of the handle 25 are guided to slide along the guiding
surface 2423 of the two pushing parts 242, so as to make the two
lateral rods 252 unlock to rotate smoothly, thereby achieving the
effect of improving smoothness in operation.
[0035] The present invention disclosed herein has been described by
means of specific embodiments. However, numerous modifications,
variations and enhancements can be made thereto by those skilled in
the art without departing from the spirit and scope of the
disclosure set forth in the claims.
